I filtered the flour in this recipe and the cake came out real well. At first I thought, that the mix was too watery and that it wasn't going to come out well. But I baked it for 45 minutes and it came out very good. On a final note I used hot water, instead of cold water. I've read somewhere that using hot water is a lot better. Another thing I think that using water instead of milk is better, because milk is too heavy and some times it prevents the cake to rise
